Absolutely no problem, I was just curious why the preamp of the 7000A would be worse? I feel more comfortable having the power on volume limiter of -20dB on the 7000A to save my speakersIs it really a problem that needs to be solved if @walburg just found the best connection between the WiiM Ultra and the 7000A and for him it happens to be using the Ultra as a pre-amp and the 7000 in power amp mode?
